A Grunt task to launch a selenium server.


Load the task:


Call the task:

grunt.registerTask 'e2e-tests', [ 'selenium-launch', 'cucumberjs' ]

Use the settings exported to the environment to connect to the correct instance:

var driver = new require("selenium-webdriver").Builder()


Grunt Task

selenium-launch Attempt to launch a selenium instance, binding to process.env.SELENIUM_LAUNCHER_PORT. If that port is unavailable, the launcher will iterate ports until it finds one available, and then resets process.env.SELENIUM_LAUNCHER_PORT to that. The task completes when the server is running and bound. The server is automatically killed when the grunt process exits - no need to take extreme steps to ensure the process isn't left a zombie.

Environment Variables

process.env.SELENIUM_LAUNCHER_PORT If set when running grunt, defines the preferred port to run Selenium on. After the task has run, has the value of the port selenium bound on.

process.env.SELENIUM_HUB After the task has run, has the string URI for webdriver hub connection. Use this string when connecting clients to selenium.
